  1. Question 1

    Q1. A sigma (σ) bond is formed by the linear overlap of atomic orbitals. This bond is characterized by:

    • A) Maximum electron density on the bond axis
    • B) Electron density above and below the axis
    • C) Formation by parallel overlap of p-orbitals
    • D) Lower bond energy than a pi bond

    Answer: Maximum electron density on the bond axis

    Explanation: Head-on overlap creates a stable, symmetrical sigma bond. Option B refers to pi bonds formed by lateral or parallel orbital overlap.
